VB.NET 10 : Optional Nullable Parameter

2009-11-08T06:56:00Z

If you want to assign Nothing to the optional parameter in VB.NET 10, it is just like to obvious now, Sub Main() 'Passing value for the optional parament _age MyFunc( "Wriju" , "wriju@contoso.com" , 30 ) 'No value is supplied for the optional parament _age MyFunc( "Writam" , "writam@contoso.com" ) End Sub Sub MyFunc( ByVal _name As String , ByVal _email As String , Optional ByVal _age As Integer ? = Nothing ) Console .WriteLine( "Name={0}, Email={1}, Age={2}" , _name, _email, _age.ToString()) End...(read more)

VB.NET 10 : Multiline Lambdas

2009-11-08T06:36:00Z

With implicit line continuation VB.NET 10 now allows you to write the multiline Lambdas. That means like your normal Functions you can write functions under Lambdas. So now you may write like, Dim arrInt As Integer () = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 } Dim myFinc = Array .FindAll(arrInt, Function (n) If n Mod 2 = 0 Then Console .WriteLine( "{0} is Even" , n) Else Console .WriteLine( "{0} is not Even" , n) End If End Function ) Namoskar!!!...(read more)

Parallel Computing: PLINQ

2009-11-02T14:48:00Z

Visual Studio 2010 has new API for LINQ (Language Integrated Query). This helps us to implement the power of Parallel Computing in declarative manner. LINQ without Parallel Extension It will take 3 sec for 28 thousand elements. static void Main( string [] args) { Stopwatch sw = Stopwatch .StartNew(); DoIt(); Console .WriteLine( "Elapsed = " + sw.ElapsedMilliseconds.ToString()); Console .ReadLine(); } private static void DoIt() { IEnumerable < int > arrInt = Enumerable .Range( 1 , 4000000 );...(read more)

Parallel Computing: The new “Task” API

2009-10-30T15:08:00Z

Visual Studio 2010 has new API called “Task”. This helps us to create small pieces of work and execute in distributed manner under multi core machine. Unlike thread it has flexibility to adopt the lower number of CPU without changing code. With improved CLR thread pool local processes are not confined in local thread pool rather it can leverage the available ppol in the memory. The below I am going to show how traditional Thread and Task works. Background We have utility function which helps us to...(read more)

Seven Things to Know about Windows 7

2009-10-21T22:12:29Z

1) Simple to Use. The Snap feature arranges windows side-by-side by dragging programs. You can then pin your favorite programs to the Windows Taskbar. Finding often-used programs and files is easier with Windows 7. The streamlined user interface includes a cleaner desktop and task bar. Using the Jump Lists feature, you can place the cursor over graphic thumbnails to see a preview of recently viewed files. 2) Faster. PCs start up and shut down faster by reducing background services. PCs also sleep...(read more)

VB.NET 10 : Array Literals

2009-10-14T02:02:00Z

VB.NET has another exiting feature which helps us to declare and initialize an array without explicitly specifying the type and dimension. This infers at compile time. Good for Lazy developer like me J Dim arrInt = {1, 2, 3, 4, 5, 6, 7} 'becomes Integer() Dim arrDouble = {1, 2, 3, 4, 5, 6, 7.9} 'becomes Double() Dim arrString = {1, 2, 3, 4, 5, "Six" } 'becomes String() Dim arrString2 = { "One" , "Two" , "Three" } 'becomes String() Dim arr2D = {{1, 2, 3}, {4, 5, 6}} 'becomes Integer(,) Namoskar!!...(read more)

VB.NET 10 : Nullable Optional Parameter

2009-10-14T01:31:00Z

You can create method with optional parameter and also make them Nullable. Optional with default value Sub Test( ByVal _name As String , ByVal _email As String , Optional ByVal _age As Integer = 30) Optional and Nullable Sub Test( ByVal _name As String , ByVal _email As String , Optional ByVal _age As Integer ? = Nothing ) Similarly you also may initialize the collection like Dictionary.

VB.NET 10 : Collection Initializer

2009-10-14T01:18:00Z

Another useful feature which was missing in VB.Net 9 is available in Visual Studio 2010. This provides option to declare and initialize with series of values with the keyword Form . Dim myList As New List ( Of Integer ) From {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} For Each i In myList Console .WriteLine(i) Next Similarly you also may initialize the collection like Dictionary. Dim myDic As New Dictionary ( Of Integer , String ) From {{1, "One" }, {2, "Two" }} Namoskar!!!...(read more)
